Nautic Partners-owned Aerostar Aerospace Completes Warmelin Precision Products Acquisition


PROVIDENCE, R.I.--(BUSINESS WIRE)--Aerostar Aerospace, a leading manufacturer of high-complexity, close-tolerance machined components used in critical aircraft systems, announced today that it has acquired Warmelin Precision Products. Aerostar, headquartered in Phoenix, AZ, is a portfolio company of Nautic Partners VII, L.P. and Nautic Partners VII-A, L.P., which partnered with management to acquire Aerostar in October 2015.

Headquartered in Hawthorne, CA, and founded in 1968, Warmelin is an advanced manufacturer of highly complex precision components for the global aerospace industry. Warmelin specializes in producing geometrically demanding parts using state-of-the-art, high-speed, five-axis machining techniques, allowing for rapid fabrication of critical components at a competitive cost. Specific areas of focus include hydraulic, actuation, and structural components.

Warmelin represents Aerostar’s first add-on acquisition as a part of the company’s strategy of identifying and integrating high-performing suppliers in the fragmented aerospace machined component industry. Together, the two businesses operate a combined facility footprint of over 100,000 square feet, have geographic diversity, and serve an array of blue-chip aerospace customers. Warmelin will provide the Aerostar platform with a strong presence in the Southern California region where the company hopes to continue its acquisition strategy.

Joe Muklevicz, CEO of Aerostar, said, “We are extremely happy to welcome Warmelin into the Aerostar family, and look forward to helping to support their growth alongside ours in the years to come. We believe that Warmelin’s adjacent capabilities will make the combined business a much stronger partner to our customers. We look forward to continuing the growth of our platform organically and through further acquisitions.”

Doug Horton, President of Warmelin, said, “A special thank you to our excellent Warmelin team for enabling our continued success. Warmelin is very excited to be working with both Aerostar and Nautic Partners as we continue to build the enterprise into the future.”
